All of these cards are compatible with my motherboard?
The tranfer speed would be the same if i use any of them?
Sorry if i ask silly (?) questions but i am completly irrelevant to the subject!
Three days before i thought that the only way to support a pc usb 3.0 was to buy a new motherboard which support it.
A final question,
if you buy a total new motherboard which supports usb 3.0 (out of the box) i suppose you would have better performance (tranfer speed maybe?) than by adding a usb 3.0 pci card to a motherboarch which supports just usb 2.0. Am i right?
No, you would not notice any difference in performance or transfer speed.
Boards with Built in USB 3.0 connect it to the NB using a PCIe lane, just routed internally instead of through a card, so in affect you are installing it the same as a built in one.
Some of the more expensive manufacturer's probably claim higher transfer rates, but that is limited by the drive anyhow, so you won't notice any difference.
The only caution is to verify that you have the correct pci-e slot available. Some card work with PCI-e x1 and some with a X4. You need to look at the manual for what slots you have available. Note, you can stick a pci-e x4 card in say an x16 slot.
So if i understood right i have to read at cards specification to see in which slot of motherboard it connects and then check if my motherboard has empty a slot like that.
Every usb 3.0 pci-e card is going to work fine if it is connected to the right slot, without performance differences (minor maybe?)!
Am i right?
There may be some performance differencies based on the on-card controller. Recommend that you read the user reviews to pick the best one.
And yes on picking the correct slot. Most mother boards have pci-e x1 slot available. X4 slots may or may not be available, But the x4 will work in an x16 slot.
